IoT Battery Life Calculator
Estimate how long a sensor node runs on a battery from its active current, sleep current and wake interval.
Average current = (active current × active time + sleep current × sleep time) ÷ cycle time. Battery life = usable capacity ÷ average current, where usable capacity is the rated capacity after your derating (temperature, ageing and self-discharge).
